Geometry Calibration in Tomography with a Differentiable Ray-Based Model
Youssef Haouchat, Aleix Boquet-Pujadas, Sepand Kashani +2
Geometric misalignments between the nominal and true acquisition parameters in tomography degrade reconstructions. We propose a framework that jointly reconstructs the volume and c…
SplineSplat: 3D Ray Tracing for Higher-Quality Tomography
Youssef Haouchat, Sepand Kashani, Aleix Boquet-Pujadas +2
We propose a method to efficiently compute tomographic projections of a 3D volume represented by a linear combination of shifted B-splines. To do so, we propose a ray-tracing algor…
Sensitivity-Aware Density Estimation in Multiple Dimensions
Aleix Boquet-Pujadas, Pol del Aguila Pla, Michael Unser
We formulate an optimization problem to estimate probability densities in the context of multidimensional problems that are sampled with uneven probability. It considers detector s…
How accurate is mechanobiology? A statistical test of cell force
Aleix Boquet-Pujadas
Mechanobiology is gaining more and more traction as the fundamental role of physical forces in biological function becomes clearer. Forces at the microscale are often measured indi…
Inverse Measurements in Active Nematics
Aleix Boquet-Pujadas, Jérôme Hardouïn, Junhao Wen +2
We present a framework to take new measurements in nematic systems that contain active elements such as molecular motors. Spatio-temporal fields of stress, traction, velocity, pres…
Convex Quantization Preserves Logconcavity
Pol del Aguila Pla, Aleix Boquet-Pujadas, Joakim Jaldén
A logconcave likelihood is as important to proper statistical inference as a convex cost function is important to variational optimization. Quantization is often disregarded when w…
Artifacts in optical projection tomography due to refractive index mismatch: model and correction
Yan Liu, Jonathan Dong, Cédric Schmidt +3
Optical Projection Tomography (OPT) is a powerful tool for 3D imaging of mesoscopic samples, thus of great importance to image whole organs for the study of various disease models…
